There are no tests marketed or sold to give a conclusive negative test earlier than 3 months post exposure.
okey, thanks sir,
One more doubt.. i read on several websites, that a DUO test taken after 28 days is conclusive.. but still some people say the one after 3 months is conclusive, and some say after 6 months .. whats the correct window period ?
PCR-RNA would not be the test to take. They are not approved to be used to screen HIV. You can take a DUO test now if you like but you will still need to retest at 3 months post exposure to obtain a conclusive test result.
